The letter to Sajid Javid said: “We are in close touch with our local police force and we are assured that they are doing the best job they can in circumstances which are unprecedentedly difficult.

"But despite their professionalism and dedication, without the proper resources it simply isn’t enough. This is a national emergency which is playing out on the streets of our constituencies and we implore you to take urgent and decisive action.

"Nothing can be more serious than the security of our constituents and the safety of our streets and communities, and we are urging you to set up a taskforce on violent crime for Brighton and Hove, as part of a comprehensive strategy both to prevent these crimes from happening and tackle their root causes.”
